IMPROVEMENT IN THE 'GUT-OFF OF ELECTED-MAGNETIC ENGINES.

To WHOM I MAY Coronas:

Be it known that I, LEwIs H. hICCU IiLOLGI I, of Richmond, Indiana, have invented certain new and useful Improvement-sin Electro-llilagnctic Engines; and I do hereby declare thefollowing to be a full, clear, and exact description of the same, reference being bad to the drawings which accompany this specification, and form a part of the same, and to the letters of reference marked thereon. In the drawings Figure 1 is a perspective view of my improvement.

Figure 2 is a perspective view of the armatures and vibrating shaft.

Figure 3 is a bottom view of my improved engine, showing the reciprocating arrangement-for changing the current of electricity and the conductingwircs.

In fig. 1, AA AA represent the framing, which is of a rectangular form, and may be made of any convenieut size. BB and B B represent a pair of magnets, situated one below the other; and D D and D D, a similar pair of magnets placed one below the other, and occupying the same relative positions in the frame, being placed opposite each otherand'held in the required position by theset-screw N, which operates the magnet throughthe plate I which is the eross-headof saidmagnetr Thejvibrating shaft C is provided with nu axle, G, upon which it rests, and which is hung on the centres I I, and is secured upon said axle by the'nuts H H. Equidistant from said axle, and attached to said vibrating shaft C, and upon each side of. the same, are armature plates, E E, above the axle, and F F below the same, at distances to correspond with the cores of the upper and lower magnets heretofore described; These armature plates are attached firmly to each other respectively by the end pieces e ee e, secured in anysuitable mannerto secure the requisite 'strength. The lower end of said vibratingjshaft terminates in a rounded form, the uses of which will be hereinafter described. Attached to the upper end of the vibrating' shaft C, by means of a .wrist-pin, is a pitman, J, the opposite end of which is connected suitably to a plate-wheel, K, by a. crank-pin, it, revolving upon asuitable shaft which carries the balance-wheel L. The metallic posts M M support the outer ends of the magnets and are sustained by the cross-pieces of the framing, each one of said parts being provided with set-screws NN, by-which the magnets are propelled forwardor back in the frame as may be required for the purpose of increasing or diminishing the force of the magnets upon the armatures. The dotted lines a a a a represent a suitable metallic framing, placed at the inner ends of the magnets, firmly attached to the framing and properly arranged for the support of the inner ends of the said magnets.- The posts 0 O are fitted to receive the battery wires, and are-suitably secured to the upper end piece of the framing A A. W is a switch-lever, pivoted upon the framing, and used to connectand disconnect the electric current with the magnets by which the engine is put in motion or stopped at pleasure. Q, fig-B, isaioross-framing occupying the centre section of the bottom of the machine, and to which are attached the devices for changing the cle'ctriccurrent to each pair of magnets alternately throughthe operation of the-lower portion of the vibrating shaft- C. To effect thisa frame, R, is provided inthe form of a cross-head sustaining the rods TT, and provided upon the side opposite from the rods T T with adjustable stops S S. These stops are made adjustable for the purpose of allowing more or less throw of the rods T T, as may be required. The rods T are held in position by set-screws 5 and 6, fig. 3. The rods T T are composed of brass or other metallic'conducting material, witha core terminating in a protruding point of glass or other non-conducting material. At the termination of each throw of the rods T T, the conducting portion of the rodcontinues the. electrical current to on'e'sct of magnets, during which'time the glass or non-conducting point being brought in contaot with the opposite post diverts the-current from the other set or pair of magnets. Each vibration of the vibrating shaft 0 reproduces this efi'ect, and a continuous vibration of the shaft (3 produces a revolution of the wheel K, by the action of the pitman J. The posts 1, 2, 3, and 4',-ar e secured to the crossframing' Q, and are providedwith openings in which the rods'T T are actuated, said openings serving both as a guide anda support. for said rods. The posts 1 and 3 are in connection with'the magnets B and D, and the postsZ and 4- are in connection with the magnets D and B, so thatlwhen the magnets B and D are charged or excited by the electric current, thearmatures E E, carrying the upper portion of the vibrating shaft, are impelled tow'ardsthe magnet B, while .the armatures F F carrying the lower portion of the vibrating-shaft ar impelled towards the magnet D, and simultaneously operate the cross-head R, whichcarries the rods T T by which the elcci i tric current is changed to the magnets D and B', by which the opposite vibration of the vibrating shaft C is protaste 2 duced which in turn changesthePcross-headR and rods T T, restoring the electric current, and thus continuing; producing a succession of revolutions as may be desired of the plate-wheel K.. By the use of the switch W the electric current is let on or taken otl' at will, and the engine is under perfect control. The nuts II II upon the axle G serve to hold thevibratingshaft O firmly in'its proper position. The vibrations of the rods 'l T are so arranged in connection with th'eiroonstruction' that they divert the current automatically from the upper and lower opposite magnets alternately during the vibration of the shaft C, and consequent revolution of the plate-wheel K.

The plate-wheel K is provided ivith additionalholes at different distances from the centre in order to compensate for the longer or shorter vibrations of the vibrating shaft 0, vlien changed by altering the positions of the stops S It ivill readilybe seen that no positive breaking ofthe current takes place at any point in the vibrations of the arm (Land as a consequence there is no loss of the electuical or exciting force upon the magnets, which may be enlarged or increased indefinitely, and anygiven number of engines may be operated by a battery having electric current sufiicient to charge the magnets of each, the only appreciable loss being the current diminution of the vital. energies of the batteries.

Among the'many advantages which are developed by my improved electromagnetic engine, the following may be referred to: y I

The direct action of the upper and lower pairs of magnets, upon opposite sides of thearmatures and vibrating shaft, above and below the central axis simultaneously, the opposite magnets being for the time dead or unexcited. 4 i

2. The arrangement by which. the electric current is automatically diverted, and sull'ers no break in its transition from-one pair of magnets to'the other pair of magiretstand vice vrsa'.

I 3. In so arranging the changing devices by which the current is diverted, as that the length of traverse or vibration of the vibrating shaft-may be in ercas'edordiminished :is maybe desired.

4. In the manner of making the magnets adjustable in relation to the vibrating shaft by which the power ofth e engine is regulated in proportion to the relative distance between said magnets and the armatures upon the shaft 0.

Having thus fully described my said improvement, what I claim as new, and desire'to secure by Letters Patent, is- I i I The compound rods T T, cross-head R, and posts 1, 2, 3, 4, constructed and operated substantially as herein set forth and described.
